WILLIAM BAXTER GLISSON, OF RUTHERFORD, TENNESSEE.

VENTILATION SYSTEM.

Application filed May 4, 1921.

To all whom it may concern.

Be it known that I, WILLIAM B. GLIssoN, a citizen'of the United States, residing at Rutherford, in the county of Gibson and State of Tennessee, have invented certain new and useful Improvements in Ventilation a warm climate or for the occupancy of tubercular patients, and aims to provide a novel and improved structure of that kind having means for the circulation of air to keep the interior cool and fresh for the comfort and benefit of the occupants.

Another object is the provision of novel means for the entrance of air to the fan, and for the flow of air to the several rooms so as to provide for a good flow of air through each room.

With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement as described and claimed, it being understood that changes can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a plan view of the structure, portions being broken away.

, Fig. 2 is a vertical section on the line 22 of Fig. 1.

The building is constructed with a main central room 5 having the ceiling 6 and a roof 7, and said room is of polygonal outline, especially on the inside, and has eight sides as shown, although there may be more or less number of sides. The building has a suitable floor 8, and can have a cellar 9 in which the fan-operating engine 10 can be located.

Sleeping rooms or chambers 11 extend from the several sides of the main room 5, excepting at one side of the main room which has a door 12 for direct ingress and egress. Said rooms or chambers 8 thus radiate from the main room, and the partitions between the rooms 5 and 11 have doors 13 for passage from one room to another, and the rooms 11 have doors 14 at their outer ends Serial No. 466,856.

providing for direct entrance and exit as well as ventilation. The rooms or chambers 11 may each contain a bed or cot 15, and the outer end wall of each room 11 has a screened ventilating transom 16 above the door 14, so that the transom can be used for ventilation, instead of leaving the door 14 open.

In order to create a forced draft of air within the building, a vertical fan shaft 17 is located centrally within the room or chamher 5, and extends through the floor 8 and ceiling 6 with the lower end journaled in a suitable bearing 18 underneath the floor 8 and upper end of said shaft journaled in a bearing 19 above the ceiling 6. The shaft 17 is rotated by the engine 10 through a suitable connection, such as a flanged pulley 20 on the shaft 17 connected by a belt 21 with the engine. The fan 22 is secured on the shaft 17 near the ceiling 6 and has any suitable number of blades, and is rotated in a direction to create a downward whirling flow of air within the room 5.

A table 24; located centrally in the room 5 can-be used by the occupants, and also serves to protect the shaft 17 which extends centrally through the top of the table, there by preventing the occupants from coming in contact with the shaft. If an oil lamp is used for light, it is preferable to provide a metal shield 25 on the table 24 over the lamp to prevent the downward current of air from extinguishing the flame.

That side of the room 5 which has the entrance and exit door 12 is provided with a large window 26 for the entrance of light.

The partitions between the rooms 5 and 11 have screened openings 27 slightly below the plane of the fan 22 for the flow of air into the rooms 11, and baffies 28 extend downwardly from the ceilings of the rooms 11 past the openings 27 to provide channels or passages 29 leading downwardly from the openings, so that the air is directed downwardly and outwardly across the beds or cots 15 to pass out through the transoms 16 or the doors 14L if such doors are left open. In this way a current of air is constantly delivered from the fan through each sleeping room or compartment to provide for thorough and efficient ventilation.

Inwardly extending air deflectors 23 are carried by the partitions between the rooms 5 and 11 at the lower edges of the openings 27 and those ends thereof which the fan blades approach when moving over said openings, whereby the downwardly whirling current of air created by the fan along said partitions is caught by said deflectors and directed through the openings 27 The fresh air enters the building above the fan 22 through a pair of air inlet channels or passages 30 extending from under the caves of the roof 7 over the ceiling 6 to openings 31 in said ceiling near the center thereof. In order to control the entrance of air, a valve 33 is provided for each opening 31, and. said valves are hinged, as at 34, to the ceiling, at the edges of the openings 31 opposite to the air inlet channels 30, and the free edges of said valves are movable across the inner ends of said channels, whereby when the valves are raised, the air passes from the channels 30 under the valves and down through the openings 31 to the fan 22. The valves 33 are controlled by means of cords 35 connected to such valves and passing over pulleys or guides 36 above the channels 30 and thence down into the room 5 in which cleats 37 or other means are provided for fastening the cords to hold the valves raised. Removable screens 32 are provided for the outer ends of the channels 30 to exclude insects, leaves, and other foreign ob j ects, and an air supply pipe 38 is connected to one side of the room 5 near the ceiling, for supplying medicated or ozonized air for the benefit of the occupants. Thus, when the valves 33 are raised, fresh air is drawn from the atmosphere at a distance from the ground, and when the valves 33 are closed the air is drawn in through the supply pipe 38 which can lead to a medicator or ozone device (not shown) or the valves 33 can be partially opened, so as to mix the medicated and fresh air.

The building can be made in any suitable height and can be of one or more stories and a group of the buildings can be arranged for the use of a single engine. Thus, a flanged pulley can be secured to the upper end of y the shaft 17 above the ceiling 6 from which a belt 46 can run to a similar pulley on the fan shaft of the adjacent building, and said belt can pass through a dormer Window 47 on the roof 7.

The operation and advantages of the structure are apparent from the foregoing, it berooms, a rotary fan within the upper portion of the central room for directing air downwardly in the central room from above said openings with a whirling motion, and an L-shaped deflector within the central room extending along the lower edge and one end of each of said openings whereby part of the downwardly whirling current of air is caught by the deflectors and directed through said openings into the radiating rooms.

2. A structure of the character described comprising a room having an opening in the ceiling thereof, a fan operable under said ceiling for drawing air down through said opening and delivering same downwardly within the room, an air inlet channel leading" to said opening, and a valve for closing said opening in the ceiling andadjustable for controlling the flow of air from said channel through said opening. 7

3. A structure of the character described comprising a room having an opening in the ceiling thereof, a fan operable under said ceiling for drawing air down through said opening, and delivering same downwardlyv within the room, an air inlet channel leading from one side to said opening, a valve hinged to the ceiling over said opening so that its free edge is movable across the inner end of said channel, and means for controlling said valve. g

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM BAXTER GLISSON.
